ThebarsB are view of my complete '1 mputed ea? d view of my improvedfgrid ement ofthe sup- L I. 1 Similar letters refer" to. similar parts I and support the same near each end of the latter but where said bars A are of more than average length, one or more intermediate bars B may be employed. Suitable nails D secure the parts A, B, together and a small portion of bitumen, or a material sold under the registered trade mark Avebane or other similar material E, is placed in the bottom of the'recesses C, (see Fig. 2), which during the nailing operation becomes flattened out, surrounding the nail connection, protecting same from corrosion, and rendering the oint gas tight at this part.

Two of :the above-described sections go to make a complete grid by being arranged with the bars B back to back, (see Fig. 7), the pairs of bars A being arranged in the latter so that upon assembly as aforesaid,

the pairs o'f'bar's' in one row break joint with the pairs 'o'f bars in the other row for the purposes-aforesaid. F is a dowel orprojection secured to one of the bars B and normally, loosely fits a corresponding recess in the other bar B 01"- each grid to revent one or the other of these sections relatively shifting their positions after being laid in the purifier. V

Byth'i's construction of grid, (see Figs. 7

*ancl9), pockets "G are forme'zd-therein between each two pairs of bars A in the upper row,

'a-n'd terminating between each pair of bars A in the bottom row, the sides of these bars assisting the purifying material to build up in a loose porous condition and prevent its escape to the layer below. Co'rrespondingly shaped pockets or cavities H on the underside o'f the grid, alternate with the pockets G and give access tothe gases filtering through the layer of material below, which are thereby distributed to the said pockets G uniform- 1 1y throughout the whole area ofthe purifier, resulting in maximum filtration of the gases passing through the same and the maintenance of a uniform density ofthe purifying "material throughout. The shape of :the support bars-and the corresponding recesses in the bearer bars dennonstrate when the two sections are secured together, a grid of exner o f a'nd means for securing the said bars to the bars B, and in the length of the latter. Where the bars A are rectangular in shape the o posing sides of each pair are parallel, and the space between his uniform :narrowwidth, which ordinarily would similarl-i affect andweaken the rib J formed in the bars B were the bars A to be similarly recessed "therein. To strengthen this rib I form a suitable rebate K in the said oppos- "ing sidesof the bars A where they engage the bars B, which correspondingly Widens and strengthens the said rib J, (see Fig. 12), as desired. To secure the bars A to the bars B, I form holes or recesses L in both, into which are driven screw-nails D of the kind shown at Fig. 13, of slightly larger diameter; the pitch of these nails is such as to cause them to rotate or turn when being views illustrate further modifications in the construction of my improved grid, and are mainly subdivisions of the grids shown at Figs. 14 and 15,0r, in which different shapes of bars A and B are employed, or in the relative arrangement thereof, and in the means for securing the said bars together-to form the grid. In'some cases dowelsN are passed through both barsA and B, and are pre- 1 vented from shifting their positions by nails D driventhrough both the dowel N and the bar A. V 7

What I claim as my invention, and "desire tosecure by Letters Patent is 1. A grid for gas purifiers comprising carrying means, support members rhomboidal in cross-section arranged in rows above and below said means and engaged therewith, the members of each row belng arranged in pairs with the spaces between the members of each pair differing in Width from the spaces between adjacent pairs, the pairs of support members in one row positioned to break joint with the pairs of members in the other row, the said support members formin alternate pockets for the reception of purifying material and the passage of gas.

*2. A grid for gas purifiers comprising bearer bars, support members-rhomboidal in cross-section arranged in rows "and secured upon opposite'sides of said bearer bars with the bearer bars secured to eachother, the rows of supporting members being arranged in pairs with the spaces between the membersof each pair less than the space between adjacent pairs, the pairs of support members upon the upper side'of the bearer members positioned to break joint with the support members on the lower side ofsaid bearer bars to form pockets containing purifying material supported by the lower row of members alternately with corresponding spaces for distributing gas to the purifying material, the said pockets being triangular in cross section with the cenfroiiting Walls of the support members ihalignm'ent.

A-grid for gaspnrifiers comprising pairs of superposed detachably associated bearer bars, support members arranged in rows above and below said bars and secured thereto, the members of each row being arranged in pairs with the spaces between the members of each pair difiering in width from the spaces between adjacent pairs, the pairs of support members in one row positioned to break joint with the pairs of members in the other row, the said support members forming alternate pockets for the reception of purifying material and the passage of gas. 7

4'. A grid for gas purifiers comprising detachably associated'carrying means arranged v back to back,- support members arranged in pairs with thespace between the members of each pair differing in' width from the space between adjacent pairs, a row of said support members being secured'to opposite sides of the carrying means, the pairs of said members in one row positioned to break joint with the pairs of members in the opposite row.

5. A grid for gas purifiers comprising detachably associated carrying means arranged back to back, support members rhomboidal in cross section arranged in pairs with the space between themembers of each pair difs fering in width from the space between adjacent pairs, a row of said'support members being secured to opposite sides of the carrying means, the pairs of said members one row j 7' positioned" to break joint with the pairs of members in the opposite row. In testimony whereof I name to this specification.
